In general, if a function takes 3 arguments, and you pass it two, then
you really should expect trouble since it's going to go ahead and use
some randome system trash as it's third arg.  I'm not in a position to
go digging around in the source code to find out just what that
function does with that arg., but it's not surprising that giving it
something meaningless makes it blow up sometimes.
